Visible index



the body of the card at either side Patented June 17, 1930 UNITED STATES PATENT OFFICE ALWIN VON A'UW, OF BROOKLYN, NEW YORK, ASSIGNOR TO BOORUM & PEASE COM- PANY, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK VISIBLE INDEX Application filed May 17,

This invention relates to the overlapping type of visible index card having a hinged slidable mounting and is in the nature of an improvement upon cards having ears outside 7 and parallel to those sides.

One object of this invention isto provide a card adapted for rapid and accurate interengagement with similar cards to produce a visible index, another object of the invention being to provide a form of card which Will engage the adjacent card positively. Other objects will be made plain as the cards are 7 described. j

In the drawings Figure 1 is a plan view of a card made according to my invention,

Fig. 2 is a plan view of part of a panel showing a number of my cards mounted thereon;

F 3 is an exaggerated longitudinalv section, taken on the line 3-3 of Fig. 2, looking in the direction of the arrow;

Fig, 4 is a perspective view of the cornersv of several cards interengaged with each other but not yet inserted in the panel, while Fig. 5 is an edge view of one of mynew cards. 7 According to my invention the cards 12 are adapted to be interengaged with each other and to'be mounted in a panel in hinged relation ina mannersimilarto that shown; and described in my United States Patent No. 1,649,763 dated November 15th, 1927,.

in which lateral depending ears form the suspending andspacing means. As set forth in that patent, the card may conveniently be hinged, preferably on a line With, or just be low a line joining the upper ends of the incisions between the depending lobes of the ears and the free sideedges 13 of the card.

Making the ears and the upper part 19 of the card integral with the record portion 16 of the card, is optional. I have found that ,in the assembling of the cards, the depend- 1928. Serial No. 278,587.

ing' cars 14 sometimes get on top of the pending lobe 17 can be obtained if desired 7 a by hot-pressing the card at the time the card is being manufactured. v

To further insure the depending ears finding its way under the car of the card below, I sometimes find it convenient to make the car 14 with an upper lobe 24 and to give this upper lobe a permanent bend which will make it lie at an angle ventral or anterior to the body of the card (Fig. 5).

This permanent ventral bend of the upper lobe 24 may be'obtained by hot pressingthe card at the time the card is being manufactured. v e;

Aswill be seen from Fig. 4, when a c is inserted at thetop of a column, the dorsally bent lower lobe of the depending ear of the card being inserted, will easilyand automatically slide under the ventrally bent upper.

lobe .of the former top card of the column.

Similarly when a card'is being inserted at the bottomof the column, the ventral angle of the up'per'lobe of the new card, will auto- -matically slide up over the dorsally bent depending lobe of the ear of the former bottom card; ,Likewise when the cards are in a panel 10, and a newcardis to be insertedinto the middle of a column, the two cards between which it is to be inserted are separated to a distance about equal to the overlap between the cards, then one ear isinserted' underits corresponding flange 11 of the panel. The depressed dependingtip :35 of the'lower lobe 17 will automaticallyv slide under the up- I so andnot to the top 'depending lobe at either side of turned upper lobe 24 of the card below, while the upturned upper lobe of the card being inserted will automatically ride up over the depressed depending lower lobe of the card already in the panel above the card being inserted. Then the card being inserted is flexed in the middle, and the other ear inserted under the other flange with similar result.

The upper lobe 24 of the ear may be formed by making the slight notch 23 at the point of junction of the ear to the top 19 of the body of the card. The ventral bend is preferably given only to the upper lobe 24c of the ear, 19 of the card, for it is desirable that the bodies of thecards lie fiatly upon the panel, to give a flat working surface.

It is desirable that the card be notched only very slightly at 23, so that there will be no deep nesting between the cards. A notch of say of an inch or less will provide an ample upper lobe to be given the desired ventral angle, but will not cause inconvenient nesting.

Fig. 8 is termed exaggerated, because in normal posit-ion the record portion 16 of each card would tend to lie practically in the same plane as the top 19, instead of meeting 19 at an'arc, as shown in this figure. The figure is drawn to show more clearly the relative positions of the ventrally bent upper lobes and dorsally bent lower lobes'when a number of cards are interengaged with each other.

I claim 1. A visible'index card comprisinga body portion in combination with an ear having a portion adjacent to the upper edge, the lower tip of said ea-rsbeing bent at'an angle dorsal to the body of the card.

2. A visible index card comprising a body portion in combination with anearhaving a depending lobe at either side of said body portion adjacent to the upper edge, thelower tip of said ears being hot-pressed to lie-dorsal to the body of the card.

3. A visible index comprising a'panel having inwardly facing opposed flanges in combination with a series of overlappingcards each COHTPIISIHg' a body portion overlying the body portion of the card below and an ear having a'depending lobe at each side of the body portion adjacent to its upper edge underlying the corresponding flange and the ear of the cardbelow, the lower tip ofeach ear being permanently bent at an angle dorsal to'the body of the card, the body portion being hinged on a line joining the points of sev erance between the body portion and the depending lobes of the ears. V

" '4. A visible index card comprising abody portion in combination with anear at either side of said body portion adj acentto the upper edge, said body portion being hinged on a line reaching from one free side edge of said said body body portion to the other,'each ear having an upper lobe and a depending lower lobe, said upper lobe being bent to lie at an angle ventral to the body portion of the card, and the tip of the lower lobe being bent to lie at an angle dorsal to said body portion.

5. A visible index card made of one integral piece of sheet material comprising a body portion in combination with an ear having a depending lobe on either side of said' body portion adjacent to the upper edge, said ears being separated from the body portion below the juncture between said body portion and said ears, and being slightly separated rrom said body portion above the uncgral piece of sheet material comprising a body portion in combination with an ear on either side of said body portion adjacent to the upper edge, said ears having an upper lobe anda depending lower lobe, said upper lobe being hot-pressed to lie at an angle Ventral to the body portion of the card, andthe trip of the lower lobe being hot-pressed to lie at an angle dorsal to said body portion.

7 A visible index card comprising a body portion in combination with suspending and spacingmeans outside said body portion comprising an ear joined thereto on each side adj acent the upper edge thereof, each ear havinga downwardly hanging lobe, said body portion being hinged on a line joining the points of severance between the body portion and the downwardly hanging lobes of the ears,

said ears having upper lobes above the "hinge line and lateral to the body portion, said up- 7 per lobes being pressed to lie atan angle ventral to the bodylportion and the tips of said downwardly hanging lobes being pressed to lie at an angle dorsal to the body portion of the card. v s j V 8. A visible index comprising a panel "having lnwardly facing opposed fianges'in combination with a series of overlapping hinged cards each comprising a body portion overly ing the body portion of-the card below and an car at each side of the body'portion adjacent to its upper edge and underlying the corresponding flange said ears having an upper ';lobe formed to he at anangle ventral to the body portion of the card, and a depending lower lobe having its tip formed to heat an angledorsal to said body portion, each lower lobe underlying the ear of the card below.

' 9.;A visible index comprising apanel having inwardly facing opposed flanges'in combi- -nation with a series of overlapping cardseach comprising a'body portion overlying thebody portion ofthe card below and an ear at each side of the body portion'adjacent-to its upper edge said ear having a depending lobe underlying the corresponding flange and the ear of the card below, said ears being slightly separated above the juncture between the body and ears to form an upper lobe, said upper lobe being permanently pressed to lie ventral to the body of the card andthe tip of the depending lobe being permanently pressed to lie dorsal to the body of the card.

In testimony whereof I ha e signed by name to this specification.
